    摘要: The present invention provides methods and compositions for photodynamic therapy. The composition comprises ceramic nanoparticles in which a photosensitive drug/dye is entrapped. The ceramic nanoparticles are made by formation of a micellar composition of the dye. The ceramic material is added to the micellar composition and the ceramic nanoparticles are precipitated by alkaline hydrolysis. The precipitated nanoparticles in which the photosensitive dye/drug is entrapped can be isolated by dialysis. The resulting drug doped nanoparticles are spherical, highly monodispersed, and stable in aqueous system. Irradiation with light of suitable wavelength of the photosensitizing drug entrapped inside nanoparticles resulted in generation of singlet oxygen, which was able to diffuse out through the pores of the ceramic matrix. The drug loaded ceramic nanoparticles of the present invention can be used as drug carriers for photodynamic therapy.

    摘要: The present invention provides a method for imaging a biological specimen using non-linear optical properties of certain materials. The method comprises the steps of providing an aqueous dispersion of ZnO nanocrystals; contacting a biological specimen with an aqueous dispersion comprising ZnO nanocrystals; exposing the biological specimen to input electromagnetic radiation having a wavelength of from 600 to 1500 nm; recording the nonlinear output electromagnetic radiation; and generating an image of the biological specimen based on the nonlinear output radiation.

    摘要: A distributed balanced tree having a plurality of nodes distributed across a plurality of servers is accessed. Version information associated with a node of the distributed balanced tree is retrieved. Validity of a lookup transaction performed on the balanced tree is determined by verifying a version value of only the leaf node accessed during the lookup operation against the retrieved version information.
